BMS Main X

Strings controller

Modular BMS for 24-1000V batteries

Main X controls up to 8 batteries connected in parallel, each of them is managed by the BMS Main 2.1. It limits the charging and discharging currents of the whole battery and dynamically turns on and off the parallel batteries to keep them balanced.
